Cooling load in kw is increase the temperature of the water before enter the cooling tower, thus the differential heat energy level is high compare to surrounding temp., so it will transfer heat more to surrounding and leave the tower with low temperature, and it will become more like to approach the wet bulb temp., this happens if the variables such the water flow, and the air velocity is kept constant.

What does CDB stand for in air conditioning?
CDB is used in HVAC in terms of air conditioning. The temperature of air is measured by a standard thermometer with a dry sensing bulb to determine CDB.
Examples of closed loop control system?
A SYSTEM is any active device if left as open loop it will saturate one way or the other if the gain is ample. To control a system it must have some feedback to determine ts linear operating capabilities. As an example an airplane taking off at las Vegas the cabin will be pressurised to -1000 feet from the ground and maintain a rate of climb to even 50.000 feet with a delta of 17 PSI The cabin pressure as a system will maintain this delta by close loop control otherwise we will need oxygen if flying. INTERESTING?
If wet bulb temperature is 35 and outlet water temperature from cooling tower is 25 then the cooling tower approach will be effective and what is the solution?
The Approach is the difference between wet bulb temperature and outlet water temperature from cooling tower. That means , in this case, Approach = 35-25=10 degrees.
How do you calculate capacity of cooling tower in terms of tonne?
calculation on mass flow rate, wet bulb temp, approach, range & condition of cooling tower installation.
What is approach of a cooling tower?
Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat fromcooling water. The make-up water source is used to replenish water lost to evaporation. Hot water fromheat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment usedto reduce the temperature of a water stream by extracting heat from water and emitting it tothe atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly (Figure 1). Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.
What does a cooling tower in an industrial ac system acts like a?
It Tries to bring down the hot water temperature to Wet Bulb temperature. Therefore does cooling. [ebolton] The refrigerant in the AC system picks up heat from the air conditioned space by turning it from liquid to vapor in the evaporator. Within the cooling tower, the refrigerant turns back to liquid in the condensor, releasing heat to the water in the tower, which itself evaporates releasing the heat to the atmosphere.[eboton]
What does the principle of the wet-bulb and dry-bulb thermometers state?
Evaporation causes cooling.
How does a light bulb demonstrate the heating effect?
by the radiation in the filament it throw out heat . this way the bulb demonstrates the heating effect. :D
What is the effect of humidification on wet bulb temperature?
wet bulb temparature will increases
Why isn't the thermometer's bulb made of metal?
Metal has a high co-efficient of expansion and would show the wrong temperature by expanding to give more volume in relation to glass on heating and opposite effect when cooling
What is the difference between cooling and chilling?
Chilling is the reduction in temperature of the required solvent below than its wet bulb temperature while the rest is considered as cooling i.e. if we are only reducing the temperature of solvent to an extent such that the final temperature is above its wet bulb temperature than it will be considered as COOLING.
What effect of current is utilised in bulb?
Heating effect of electric current.
Is humidity high or low if the wet and dry bulb readings are close to each other?
The humidity is high. The air is saturated, so the water in the wet bulb is not evaporating and cooling the bulb.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
